WD-40 Specialist® Penetrant Spray quickly release rusted, corroded, stuck, or seized nuts, bolts, parts or fixings with ease. Working on contact, the penetrant saturates deep into seams, crevices, and threads to break down any rust that bonds parts together, rapidly lubricating and freeing them. WD-40 Specialist Penetrant spray is easy to use, highly water resistant and leaves behind a protective layer to prevent rust and corrosion from re-forming.
